How to Install Doozerd on nixOS Latest

Doozerd is a distributed data store that provides consistent, fault-tolerant, and distributed coordination. In this tutorial, we'll explain how to install Doozerd on nixOS Latest.

Prerequisites

Before we proceed with the installation of Doozerd, make sure that you have the following prerequisites:

• A running instance of nixOS Latest
• Administrative privileges

Step 1: Install Git

If you don't have Git installed on your system, you can install it by running:

sudo nix-env -i git

Step 2: Clone the Doozerd Repository

To clone the Doozerd repository, run the following command:

git clone https://github.com/ha/doozerd.git

This will create a directory named doozerd in your current working directory.

Step 3: Build Doozerd

To build Doozerd, navigate to the root directory of the cloned repository and execute the following command:

nix-build release.nix

This will build and create a binary executable under ./result/bin/doozerd.

Step 4: Install Doozerd

To install Doozerd, we'll create a nix package using the ./release.nix file. To do that, run the following command:

cat release.nix | sudo nix-env -i doozerd

This command will create a new package called doozerd. You can now check if Doozerd has been installed correctly by running the following command:

doozerd -v

This will display the version of Doozerd you installed.

Step 5: Start Doozerd Service

Now that Doozerd is installed, let's enable and start the service. To do that, create a new systemd service called doozerd.service:

sudo nano /etc/systemd/system/doozerd.service

Copy the following contents into the file and save it:

[Unit]
Description=Doozerd
After=network.target

[Service]
ExecStart=/nix/store/...-doozerd-.../bin/doozerd
Type=simple

[Install]
WantedBy=multi-user.target

Note that you should replace /nix/store/...-doozerd-.../ with the path to your doozerd binary. You can find the correct path by running:

which doozerd

Now that we've created the service, let's enable and start it with the following commands:

sudo systemctl enable doozerd.service
sudo systemctl start doozerd.service

That's it! Doozerd is now installed and running on your nixOS Latest system. You can now use it to store and access distributed data.
